Fotógrafo Service Studio Foto. Fotografia antigua California. 1918. Workers on the shipyard. SS Faith concrete ship

En esta fotografía posan, encaramados en los andamios, los obreros que, entre Diciembre de 1917 y Abril de 1918 construyeron el primer buque de hormigón armado ( ferro concrete) de USA.

La fotografía de obreros en el trabajo de sus fabricas, men at work, empieza a extenderse en las primeras décadas del siglo XX permitiendonos asi tener una fuente documental de primera mano sobre esa época.
Esta foto pertenece a un álbum, realizado por Service Studio Foto 123 Market St. El álbum perteneció a uno de los ingenieros del buque llamado Nicolson. El barco, el S.S. Faith fue un encargo del Presidente Wilson a la Shipbuilding Company de San Francisco propiedad de Leslie Comyn.

  •  This album consists of more than 100 vintage photographies mounted on a black cardboard. These high quality photos have the date on it, showing the chronologie of the construction of the concrete ship. When bought, the album had an envelope with this sentece: "Nicolson/launching of the Faith March 14, 1918". The seller indicated (and I couldn't check the information yet), Nicolson was an engineer of the San Francisco Shipbuilding Company and his image is in some of the photos. Pasted on the front cover, there were two pieces of a newspaper:
  • One with an image and the following text:

Carrying a General Cargo the concrete ship Faith. Passing through Gaillard  Cut Panama Canal en route from New York to Valparaiso on the Stone Hull has been conclusively demonstrated by this vessel, which has Weathered heavy storms an travelled thousands of miles during the past year.
 

  • Another text without image:

  • On the back cover, there was another label:

The ideal To duplicate order Nº 7633 B Made by The  J.L. Hanson Co. Chicago
